The ancient Chinese pray for recovery also includes some elements of suggestion therapy. Suggestion has both positive suggestion and negative suggestion. Positive suggestion means the patient accepts other people' s ideas completely, unconditionally, uncritically and without analysis no matter the ideas are correct or not. It exerts positive effects on psychosomatic health. Negative suggestion, however, denotes that the patient thoroughly negates and rejects other people's ideas. It has negative effects on psychosomatic health. Suggestion therapy makes use of the positive effects of suggestion to promote psychosomatic health of the human body. Meanwhile, attention should be paid to avoiding the negative effects of suggestion. More information, please read Physiological Functions of Body Fluid.

Suggestion therapy may be conducted on two occasions: one is performed in complete waking state without hypnotization; the other means suggestion is given to the patient after he or she enters hypnosis. The latter excels the former in effects. Besides, the patient also may perform positive self suggestion and repeatedly intensify the consciousness of "excellent health and recovery from the disease". In this way, visceral functions can be consequently induced to develop along an orderly direction. More information, please read Transportation and Metabolism of Body Fluid.
